Yeah, seems pretty random. Some posts that I wrote like 3 or 4 years ago still have the images in them but others don´t... I also found posts that actually have just some of the pictures, for example this one:
@phortun/amazing-nature-contest-my-ultimate-iguana-photo-collection
From what I have heard, text is stored directly on the blockchain but pictures and videos are stored in some external servers...
RE: How are the images in blog posts published on Hive stored?
